Gate input is LOW-ACTIVE?
A LOW-ACTIVE gate input means that the gate's output is activated or enabled when the input signal is at a low voltage level (typically near 0 volts). In digital logic circuits, this characteristic is often seen in components like NAND and NOR gates. For example, a LOW-ACTIVE NAND gate will produce a high output unless all its inputs are low, while a LOW-ACTIVE NOR gate will produce a high output only when all its inputs are low. This behavior is essential for designing logic circuits that respond to specific input conditions.
Which of the logic gates would detect if the inputs are different?
The XOR (exclusive OR) gate detects if the inputs are different. It outputs a high signal (1) when the inputs are not the same (one input is high and the other is low) and outputs a low signal (0) when the inputs are the same. Thus, it effectively identifies the difference between the two inputs.
Which IC digital gates requires a high on both inputs to output a high?
An AND gate
Why most IC are active low?
Most control signals in electronics are active-low signals (usually reset lines, chip select lines and so on). This stems from the fact that most logic families can sink more current than they can source, so fanout and noise immunity increase. (The reason for this is ultimately related to the fact that electrons are negatively charged.) It also allows for wired-OR logic if the logic gates are open-collector/open-drain with a pull-up resistor. Examples of this are the I²C bus and Controller Area Network (CAN).
Which logic function has the output low only when all inputs are high?
NAND
What are the differences between active low and active high SR flip flop?
Hello The difference between an active low and an active high SR flip-flop is that with the active low SR flip-flop, the system is activated when the inputs to system are zeros while with the active high SR flip-flop, the system is activated when the inputs to the system are ones.
Why is 7475 IC chip is called a transparent?
Because the data at the D inputs is passed to the Q output terminals as long as the C enable control inputs are high...it is thus said to be transparent. When the enable inputs go low, the data present at that time is latched into the register and retained.
When is the output of AND gate HIGH?
When all inputs are HIGH.

WHY on making both the inputs high in the AND Gate the output becomes high?
The output of the AND gate is high when both inputs are high because that is the definition of an AND gate. (Ouput is true ONLY WHEN Input A AND Input B are true.)
How does a memory decoder 74Ls138 function?
The 74LS138 is a 3-to-8 line decoder that takes 3 input binary signals and activates one of eight output lines based on those inputs. It features three select inputs (A0, A1, A2) that determine which output (Y0 to Y7) will be low (active), while all other outputs remain high (inactive). The decoder also has enable inputs to control its operation; if the enables are not activated, none of the outputs will be activated. This device is commonly used in memory address decoding and data routing applications.
On a VW Jetta Monsoon amp are the four sets of 16 gauge wires high level inputs or a second set of speaker outs?
high level inputs
Which IC digital gates requires a high on both inputs to output a high?
An AND gate
What is the function of enable input in a multiplexer?
The enable input in a multiplexer (MUX) determines whether the MUX is active or inactive. When the enable input is activated (usually set to high), the MUX can select one of its data inputs to pass through to the output. Conversely, when the enable input is deactivated (set to low), the MUX typically outputs a default value, often zero or a high-impedance state, effectively disconnecting the inputs from the output. This feature allows for better control over the signal flow and can prevent unwanted data from being passed through during certain operations.
Why are inverters on the output of the 74LS138 CHIP?
In high-performance memory systems these decoders can be used to minimize the effects of system decoding. When used with high-speed memories, the delay times of these decoders are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible. The DM74LS138 decodes one-of-eight lines, based upon the conditions at the three binary select inputs and the three enable inputs. Two active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented with no external inverters, and a 32-line decoder requires only one inverter.
